Establishing an Electrically Safe Work Condition

Test procedural verification steps under NFPA 70E Article 120:

Article 120: Electrically Safe Work Condition Sample Question 1 of 1
Before allowing a qualified electrical technician to make contact with de-energized electrical conductors, which mandatory verification step must be performed to declare an Electrically Safe Work Condition?
A
Turn off the main upstream disconnect switch without further validation.
B
Test for absence of nominal voltage using an adequately rated portable test instrument verified on a known energized voltage source before and after the test.
C
Place yellow warning ribbon around the substation perimeter.
D
Rely on written shift handoff documentation confirming breaker opening.
✓ Official Explanation: (B) NFPA 70E Section 120.5 mandates the three-point voltage test method (live-dead-live verification): check the instrument on a verified energized source, probe each phase-to-phase and phase-to-ground conductor to confirm zero energy, and re-test on the live source to prove meter integrity.
